中文摘要：

利用滨海新区某吹填场地，选取不同的初始固结度为变化条件，采用ABAQUS有限元计算软件对吹填地基中单桩侧摩阻力进行了计算分析，得出与固结度相关的桩侧摩阻力的变化规律，并重点探讨了由于土体固结沉降大于桩体沉降所引起的桩侧负摩阻力的变化，得出了中性点位置随初始固结度的变化规律，为今后实际工程提供了一定的参考。

英文摘要：

The text choose different consolidation degree in coastal dredger fill ,it is simulated with ABAQUS finite element software to analysis the friction .get the discipline on the changes of the friction with consolidation degree.It also probes the changes of the friction because the consolidation settlement is greater the settlement of the pile .get the discipline on the position of neutral point .it supplies reference for practical project.
